▶ Nā hiʻohiʻona：

*Pahu metala ikaika

*Uilahōʻoia hōʻoia

*Nalo ka loulou optical haʻahaʻa - max 30dB

* Me ka ʻole o EMI, RFI a me ka loop loop

* Hoʻouna ʻia ʻo Bi-di ma 1 fiber me WDM

* Pākuʻi-a-pāʻani wela me ka lako mana hoʻololi

* Loaʻa i nā ʻōnaehana kū hoʻokahi a me 3U

▶Noi:

*Hōʻike i ka palekana palekana a me ka ʻōnaehana kaʻa

* Pūnaehana kiaʻi kaʻa o ke kūlanakauhale

* Pūnaehana kiaʻi hale a me ka pā kula

*Ka nānā ʻana i nā ʻoihana (ke kahua mokulele, nā mea kanu kemika, ke alahao, a pēlā aku)

*Ka nānā ʻana i ka pūʻali koa (pale palena, pale aupuni)

*Kuhi ʻaila mana uila, hoʻolaha papahana TV

* Gymnasium (wikiō ola a hoʻouna leo leo)
